TYPEWRITING MACHINE.

Application led June 16, 1923. SeriaTNO. 645,720.

To all whom t may concer/L:

Be it known that I, GEQRGE WQRENZ, a citizen of the United States, residing in borough of Bronx, in the county of Bronx, city and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification. This invention relates to typewriting machines equipped for typing successive forms printed in succession upon fan-fold webs, as set forth, for example, in the patent to Wernery and Smith, No. 1,132,055, dated March 16, 1915, or for use with loose superposed plies of work-web.' In Patent No. 1,358,033, granted to J. A. B. Smith, November 9, 1920, vthere is disclosed one of these fan-fold typewriting machines with equipment for using therein either one of two webs, the leading end of each web being attached to a platform or frame, and either of said frames being attaohable to the typewriter carriage, while the other frame with Vits attached web rests upon the desk ofthe typewriter.. Tn the foregoing machine, when it is desired to cease typing on one web and begin typing on the other, it is necessary to detach the frame that is in use, together with its web, and place the same upon the desk'or in a receptacle, and then pick up the other frame with its attached web and secure it to the carriage of the typewriting machine. One of theobjects of the present invention is to provideamachine in which Ythe change may be made from one fan-fold web. or set of plies to the other fan-fold web or set of plies with greater celerity and convenience, and an object is to avoid the awkwardness which is involved in detaching the frames from the Vmachine and depositing them upon the desk and: then re-attaching them. i According to the present improvements,

' both fan-fold webs or both (sets of superposed plies may be led part way into the machine, each web or set of plies forming a separate unit vor pack, and both units or packs may be attached separately to the carbon-carrier which is usually employed in these machines for the purpose of facilitatingythe relative shifting between the plies of work-web and the sheets of carbon. On the carbon-carrier there are mounted, ac.-

units is carried forward and down around the platen to be typedupon.r The` other unit, however, is temporarily clipped to the carbon-carrienso that said other unit' merely moves forwardly and backwardly in idleness as the carbon-carrier moves. In other words, the carbon-carrier must havel its forward and backward movements that ordinarily accompanythe line-feeding rotation 'of the platen and therelative shifting 'movements of the carbons and work-web units, but during these forward and backward movements of the carbon-carrier' for the typing of one of the work sheet units, the other work-web unit is drawn forwardly and backwardly in idleness, being temporarily clipped to the carbon-carrier, and only'fone work-web unit at a time being fed around the platen to be typed upon. Y

Accordingly, when the typing of one form upon one of the web units orfpacks is completed, and the carbons `forI said web are shifted, and the typed form 'is torn off, said web-unit may be withdrawn from the platen and clipped temporarily to the carbon-carrier, while the lotlier web-unit may be unclipped from the carbon-carrier` andpulled forwardly and passed down around the platenand up in front thereof for typing thereon; and, when the typing off-'a kform is completed, the carbons may be shifted back and the typed form-may be torn off, and

then the web unit or pack in question may be withdrawn from the platen and again clipped temporarily 'to the carbon-carrier. Then the first web unit or pack may be released from its temporary clip and drawn forward and passed Varound the platen to type another of` the forms thereon, andso on, the webs being used in alternation. Of course, each web may be kept in use as long as it is necessary in 'order to type a' succession of forms thereon before withdrawing it from ythe platen and advancingthe other web `into typing position. i

Thus it will be yseen that thetwo sets of v carbon-carrynig-blades `may befiXed or secured upon the single kcarbon-carrier which ,appropriate web, and the ,neXt memel'eedum @an be typed either Upon the Same web 0r een the other web-unit, as occasion may requirefso that Sorting is rendered UDHQCQS- Sary and the Work iS Speeded- .Qther' -features andadvantages will hereinafterappear: a

l ,f'ligure 3 is'a= front elevation of the carbon-carrier, showing the position thereon of the `cli-ps which hold-the work units or packs.

usual, a platen 5 is mounted in a cail` riage 6, in the backofwhich is'mounted a work-frame 7 Feed-'rolls 8 and 9 cooperate with the platen in the usual manner in feeding work-sheets' or packs of work-sheets around the platen. Mounted `on the workframe- 7 is va carbon-carrier ,10, composed of a base 11 to which arefastened rollers 12, which engage rails 1:3 of the work-frame Mountedon the base 11 is a plate 14, `which carries a plurality of carbon-blades 15. Also mounted on the plate 14 are the posts 16, preferably one at each of the four corners of the plate.- The tops of the posts 16 are preferably reduced in size,` as at 17, thus Vformingshoulders 18 which support a",second -plate 19 which is provided with openings to receive the reduced tops '1T and which also has mounted thereon a pluraltity .of carbon-blades 20. Mounted near the -frontof the platesr 14 and l19 are paper clamps 21A and 22, provided with fingerpieces 23 andv 24.V The plate :14 hasprojecting from its lower surface a plurality of pins 25 which may pass tlfirou-gh corresponding openings in the base 11, and which are furnishedwith slots-26 into which may be swung keys 27, preferably vformed in the shape of pivoted Alevers which are mounted upon the'under side ofthe base 11, as Vsho'wn ein-'Figures 1 and v2.-r The keys 27,

operating in conjunction with the pins 25, serve to lock the structure formed by the plates 14 and 19 and the posts 16 to the base 11 of the'carbon-carrier.

To facilitate the backward movement of the carbon-carrier when withdrawing the carbons from a typed section of the worksheet unit or pack, there is mounted on the lower plate 14 the hand-lever 28, which extends toward the front of the machine where it isV accessible to the operator. Mounted on the rear of the work-'frame 7 are the transverse shafts 29 and 30, provided with paper-guides 31 and 32.

yIn operation a work-sheet unit or pack 33, made up of a plurality of yworksheets 33a, isl threaded into the machine over transverse shaft 29, between the carbonblades 15, after which the leading edge is bent back, and brought to a position in front of the lower edge of the plate 14, where it is fastened by the paper-clamp 21. Another Work-sheet unit or pack 34, made up of a plurality of work-sheets 34a, is threaded in a similar manner into the machine over the transverse shaft 30, between the carbon-blades 20, and the leading edge is bent back in a similar manner and brought to a point in front of the plate 1 9, where it is fastened in place by the paperclainp 22. Y V

Assuming that memoranda of two different sorts are to be typed .on the forms ed upon the work-sheet units or packs, that the first memorandum is of the sort in'- tended for the forms printed on the worksheet yunit or pack 33, the leading edge of that pack is released from its paper-clamp 21 and brought forward in the usual manner, and inserted underneath and around the platen. Upon completing the typing Vef the first memorandum on the work-sheet unit or pack 83, it may be supposed that `the operator finds the second memorandum to be one that is to be typed upon the form printed on the work-sheets-of the work-web unit or pack 34. Accordingly, the operator withdraws the work-sheet unit or pack-33 from the platen, bends the leading edge toward the rear of the machine in order to get it out of the way, and clips it in' position upon the plate 14 by means of the paper-clamp 21. The operator then releases the leading edge of the work-sheet unit or pack 84 Vfrom the paper-clamp 22, straightens it out, draws it forward, and inserts it underneath and around the platen and brings it to the typing position.

The part played bv the feed-roll mechanism ofthe machine in this insertion and withdrawal of work-sheet units'or packs is, of course, the obvious onel of releasing the rolls when the work-sheet units or 'packs are being inserted or withdrawn, and of placing them in engagement with the Workimprovements may be used Without others.v
